Default Re: (Motorized Bike Kit) Good Chain Tension Setting rear sproket

I used the spacer method when I put mine on for the first time, but mine was so close to the same size it would have been centered anyway just by eyeballing it... but using a pointer is a really good idea on these in case the hole isn't perfectly centered.
One other thing I do after I get it bolted down is to check the side to side wobble and adjust it straight by tightening and loosening the 9 bolts until straight, then tighten them all down as evenly as possible once the runout is as minimal as possible. You can fine tune it even more by using a dial indicator, but as long as it's under about 1/16" it won't pop off the chain.
